Australians used to seeing their athletes punch above their weight on the world stage might have to settle for watching also-rans unless a new way to fund sport is found. The Australian Sports Commission, which has been rebranded as Sport Australia, is considering a national lottery to support rising stars, similar to the United Kingdom. Sport Australia chairman John Wylie said the UK lottery was directly linked to that country's rising success in world sport. "There's no doubt in the long-term, the Australian sporting system to remain as successful as its been in the past will need more funding," Mr Wylie told ABC radio on Thursday. Australian sport is also looking to charity to boost hopes of gold medals and podium finishes. The Sport 2030 report, released on Wednesday, calls for Australian sport to more than double donation receipts within three years. More than $44 million was raised through the Australian Sports Foundation in 2017/18, but the report calls for that to be $100 million in 2021 and $300 million in 2030. Sport Minister Bridget McKenzie has committed to a business plan to revitalise the Australian Institute of Sport. The announcement came a day after Australian marathon champion Rob De Castella declared the AIS was dead. Mr Wylie noted the institute's maintenance bill was $16 million a year but denied it was being hollowed out. "It's evolving into being a strategic agency for sport, a system leader for Australian sport," he said. The former investment banker warned of rising global threats to sport's integrity, saying it was important to get on the front foot after a major report into the matter was released. The review, led by James Wood QC, recommended setting up a new law enforcement agency to police match-fixing and doping in Australian sport. Australian Associated Press
